Alpine Linux 3.7+
=========================================================
For building Alpine Linux dev packages, we use docker.
Install docker 17.05 or later
-----------------------------
Depending on your host, there are different ways of installing docker. Refer
to the documentation here for instructions on how to install a free version of
docker: https://www.docker.com/community-edition
Pre-built packages and docker images
------------------------------------
The master branch of https://github.com/frrouting/frr.git has a
continuous delivery of docker images to docker hub at:
https://hub.docker.com/r/ajones17/frr/. These images have the frr packages
in /pkgs/apk and have the frr package pre-installed. To copy Alpine
packages out of these images:
::
id=`docker create ajones17/frr:latest`
docker cp ${id}:/pkgs _some_directory_
docker rm $id
To run the frr daemons (see below for how to configure them):
::
docker run -it --rm --name frr ajones17/frr:latest
docker exec -it frr /bin/sh
Work with sources
-----------------
::
git clone https://github.com/frrouting/frr.git frr
cd frr
Build apk packages
------------------
::
./docker/alpine/build.sh
This will put the apk packages in:
::
./docker/pkgs/apk/x86_64/
Usage
-----
To create a base image with the frr packages installed:
::
docker build --rm -f docker/alpine/Dockerfile -t frr:latest .
Or, if you don't have a git checkout of the sources, you can build a base
image directly off the github account:
::
docker build --rm -f docker/alpine/Dockerfile -t frr:latest \
https://github.com/frrouting/frr.git
And to run the image:
::
docker run -it --rm --name frr frr:latest
In the default configuration, none of the frr daemons will be running.
To configure the daemons, exec into the container and edit the configuration
files or mount a volume with configuration files into the container on
startup. To configure by hand:
::
docker exec -it frr /bin/sh
vi /etc/frr/daemons
/etc/init.d/frr start
Or, to configure the daemons using /etc/frr from a host volume, put the
config files in, say, ./docker/etc and bind mount that into the
container:
::
docker run -it --rm -v `pwd`/docker/etc:/etc/frr frr:latest
We can also build the base image directly from docker-compose, with a
docker-compose.yml file like this one:
::
version: '2.2'
services:
frr:
build:
context: https://github.com/frrouting/frr.git
dockerfile: docker/alpine/Dockerfile
